172.16.2.189 is a valid IP address that a technician can assign to a new desktop computer. An IP address is a unique identifier that is assigned to a device on a network that uses the Internet Protocol (IP). An IP address consists of four numbers separated by dots, each ranging from 0 to 255. For example, 192.168.1.1 is an IP address. An IP address can be classified into different classes based on the first number: Class A (1-126), Class B (128-191), Class C (192-223), Class D (224-239), and Class E (240-255). Each class has a different range of IP addresses that can be used for public or private networks. 172.16.2.189 is a Class B IP address that belongs to the private network range of 172.16.0.0 to 172.31.255.255.

A cloud-hosted application is accessible over the internet and does not require a client component installed on individual user devices. This type of deployment allows employees to access the application from any location and any device with internet connectivity, which is particularly beneficial for those not connected to the corporate network.
References:The advantages and functional descriptions of cloud-hosted services are extensively covered in CompTIA IT Fundamentals and other CompTIA study guides, particularly in sections related to cloud computing and SaaS (Software as a Service).

A byte is a unit of information that consists of eight bits. A bit is a binary digit that can have a value of either
0 or 1. An IP address is 32 bits long, which means it is composed of four groups of eight bits each. Therefore, if converted to bytes, an IP address would be four bytes long. For example, the IP address 192.168.1.1 in binary form is:
11000000.10101000.00000001.00000001
This IP address has four groups of eight bits each, which are equivalent to four bytes. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 6: Infrastructure Concepts, page
